WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 328,952, dated October2'7, 1885.

Application filed March 19, 1885. Serial No. 159,477. (No model.)

whereby the plow and the colter are caused` to rise and fall in unison.

|The invention is designed more particularly as an improvement on theconstruction rep-,

resented in the application for Letters Patent of the United Statestiled by Thomas Duke on the 8th day of September, 1884, No. 142,506, theaim of the invention being to provide a colter-operating device whichshould be more acceptable to the operator than that represented in theoriginal application, and to adapt the same to be applied to plowsalready completed, as well as to those hereafter manufactured. Y

Referring to the accompanying drawings, Figure l represents a sideelevation of my attaehment as it appears when in operative position, theplow-beam being Vindicated by dotted lines. Fig. 2 is a perspective viewof the device as seen from the opposite side. Fig. 3 is a cross-sectionon the line ac 00 of Fig. l. Fig. 4 is a cross-section on the line y yof Fig.

l. Fig. 5 is a side elevation, in outline, of a plow having myimprovements attached.

Referring to the drawings, A represents a metal plate adapted to titagainst the side of the plow beam or frame, with horizontal flanges c,to embrace the upper and lower edges of the beam and assist in retainingthe device in place.

B represents a bar designed to lie against the opposite side of thebeamand connected at its upper and lower edges with the plate A by meansof fastening bolts or screws b.

At its lower edge the plate A is provided with an ear, c, recessed toreceive a journal, d, formed on the side of the vertical socket C, whichis constructed of tubular form, as

shown, or of other suitable form adapted for the attachment of the stemor spindle of the colter thereto. Vhen of tubular form, the socket isprovided with a lateral bolt or equivalent fastening device, e, tosecure the spindle of the colter thereto. At its upper edge the plate isprovided with the second ear, f,which receives and sustains the pivot orjournal of an elbow-lever, D, one end of which is pivoted to a link, g,which is in turn pivoted at the opposite end to an arm, 72., formedrigidly on the side ofthe socket O, this construction and arrangementserving to impart motion from the elbow-lever D to the socket O, whichis tipped in a vertical plane, or, in other words, about its horizontalaxis, so :as to throw the colter upward or downward,into or out of thesoil, as occasion may demand. rlhe lever D has a boss orprojectionsimilar to that on the side of the socket, seated in thesupporting-plate A, these bosses serving to relieve the fastening-boltsof a portion of the strain. The lever and the socket are confined inplace by means ot the tie-bolt E, the two eXtremities of which are bentat right angles to the body in lines parallel with each other, andpassed through the supporting-plate A, secured on the back of nutsapplied thereto. The lever D is forked at one end and provided with aseries of holes to receive the pivot connecting the same to anoperatingbar, F, which is in turn connected at its opposite end to thelever G, by which the raising and lowering of the plow is effected.

In the drawings I have represented a plow attached to the frame in thesame manner as in my previous application; but it is to be understoodthat the manner of connecting and adjusting the plow is not a materialpart of this invention, as my device may be connected with and operatedby plow-adj us'ting levers or devices of either of the various forms atpresent known in the art.

It is to be noted as an advantage of the present contrivance that it isadapted for appli cation to existing plows as well as others with outchange in their construction. Y

It is manifest that the marginal form or outline of the plate A may bemodiiied at will,

provided it is adapted for attachment to the plow frame or beam, andalso adapted to support the plow parts thereon.

It is preferred to extend the bolt E from the lever to the socket, asshown, for the reason that it serves to tie the parts together-andprevent them from being thrown out of position, the backward strain onthe lever being counteracted by the forward strain on the socket.Instead of this bolt, two independent bolts having heads thereon may beusedone for the lever and the other for the socket; or, in place of thebolts, other fastening devices,such as are familiar to the skilledmechanic,may be employed. In short, it is to be understood that thesubstance of the invention consists in the lever and the socketconnected with each other and mounted on a supportingplate, and thatmodications or variations in the details may be made to any extentwithin the range of mechanical skill.

The series of holes in the elbow-lever admit of the operating-bar beingattached thereto at different points, so as to vary the extent ofmovement of the colter.

The position of the colter with respect to that of the 'plow may also bemodified to a limited extent, as circumstances may demand, by adjustingthe supportingplate A forward or backward on the beam or frame.

Having thus described my invention,what I claim is l. The coltersupporting and adjusting attachment for wheeled plows, consisting of aplate provided, substantially as described, with means of attachment tothe plow beam or frame, a colter-supporting socket pivoted to saidplate, and an operating-lever pivoted independently to said plate, saidmembers being constructed and combined for joint operation substantiallyas described and shown.

2. The anged plate Aand fastening-bar B, with their connecting devices,in combination with the socket C and elbow-leverD, pivoted independentlyto said plate, and the connecting-link g.

3. In combination with the supporting-plate A and the socket and levermounted thereon and connected with each other, as described, thefastening-bolt E, constructed and applied as described and shown.

4. In a wheeled plow, a wheeled frame, a verticallyadjustable colter,and a plowedjusting lever, in combination with the colter, the pivotedsocket having an arm thereon,the elbow-lever, the connecting-link, andthe bar connecting said lever with the plow-adjusting lever.

In testimony whereof I hereunto set my hand,

AUGUST LINDGREN.
